Originally from Switzerland, now based in New York City, we specialize in fine vintage and antique jewelry, mostly from the Art Deco and Edwardian era. We are experts in Colored Gemstones jewelry, primarily with untreated rubies, sapphires and emeralds. Most of our items come with certificates from the world's most renowned laboratories, such as Gübelin or GIA.

We do not sell mass produced jewelry or colored gemstones that have undergone significant treatment. All treatments, or the absence of them, are fully declared and always confirmed by a corresponding lab report.

Unheated Ruby and Diamond Pendant (GIA), 14K White Gold

Unheated Ruby and Diamond Pendant (GIA), 14K White Gold

Ruby: One ruby, pear cut, 0.79 ct in weight, entirely unheated/untreated and certified as such by the accompanying GIA report. For some reason, GIA was not able to determine the geographic origin, which is why the report reads „origin: inconclusive“. That a laboratory cannot determine the origin of a ruby or sapphire happens sometimes, especially with very clean material. Please note that rubies are notoriously difficult to photograph – in real life, the color of this ruby is much nicer than the photos are able to show (please ask if you would like a detailed description of the color, we will do our best).
